FIGURE 3.

Preference for animacy for the chicks tested 3 days after hatching injected with T₃ or vehicle. To best represent the data, we used raincloud plots. Black asterisks indicate a significant difference between sexes (females red and males blue) within each injection group. Red asterisks above a red horizontal line indicate a significant difference between females of each injection group. Blue asterisks above a blue horizontal line indicate a significant difference between males of each injection group. Red asterisks indicate a significant difference from chance in females. *** indicates p < 0.001, ** indicates p < 0.01, * indicates p < 0.05. Filled red dots represent female and blue male subjects, empty dots represent outliers, which were removed from the analyses.
